What happened last week?
Happy Veteran’s day to everyone! Thank you to all veterans who have served our country and fought for our freedom. It is a blessing to our country that you were willing to sacrifice so much for the good of our country!
Here is what we have been up to in Biology this week:
Monday 11/5
Thanks to Grace L from 5th hour…
Today in class we did two labs. We started a new lab with dialysis tubes. We used the tubes and put glucose/starch/protein solution in them. We ran a Benedict, Biuret, and iodine test to see if the solution passed through the tube and which biomolecules were present.
We also did another part of our egg lab. The most important thing we learned was seeing visually how diffusion and osmosis work in a cell.The coolest part of class was seeing the color changes with the different tests we ran for the dialysis tube lab. Also, seeing what the egg looked like after sitting in Karo Syrup. Our homework is to finish the lab questions of the D.T.L. Also, you have to watch a video (under our cell unit page on Mrs. Giegler's website) and complete a survey with it.

According to Brian L from 6th hour…
We kept working on the egg lab. We also set up the dialysis tube lab and tested for monosaccharides, proteins and starches that leaked out of the bag. We added iodine at the end to test for starch. The most important thing I learned is that most membranes are semi- permeable and particles that are small enough can pass through. The coolest part of class was looking at the egg. The homework was to watch the cell membrane videos online and fill out the survey. You also need to finish the questions from the dialysis tube lab. A good test question would be “What is the difference between osmosis and diffusion?”
Tuesday 11/6:
Today we checked on the eggs one last time after they had been sitting overnight in water. The students should have seen that the egg got larger due to water entering back into the egg. Then we finished talking about the notes on diffusion and osmosis. These notes will be posted shortly online. The homework for the night was to finish the egg lab questions and work on a packet with excellent question about passive and active transport.
Wednesday 11/7:
The students were very excited today to hear that the test was being postponed to next Wednesday! We spent the day going over the packet of questions on passive and active transport and then completed a short lab where the students viewed normal red onion cells. Then we added salt water to the cells, looked at them and then flooded them with DI water. In the below video you can see what the students saw – you should ask them to explain what is happening and why! The homework was to finish the summary questions from the lab.

Thursday 11/8:
This just in from Nathan N from 6th hour…
On Thursday November 8 we took a pop quiz, finished watching the BBC video, and reviewed for the test. The pop quiz was for us to figure out how much we know about organelles and what we need to study. A cool part of the BBC video was that our white blood cells eat up the virus so we do not get sick.
Thanks Nathan! The students were given their review packet to work on over the weekend.
Friday 11/9:
Today was an institute day so students did not have to come to school :) I hope they enjoyed the day off!

What to look for...
Monday 11/12:
No School – Thank a veteran for their service!
Tuesday 11/13:
Today we are going to spend some time reviewing. We will go over the pop quiz from Thursday to go over the information and use that as a way to make sure that the students understand all of the labs from last week. Then we will do an activity to help us review by using butcher paper to write all of the information we know about different topics and any questions that the students still have. We will also use the time for each student to play “If I were writing the test…”
Wednesday 11/14:
We will take the test covering the cell and the cell processes on this day. The students will need to review information about the cell organelles, the cell theory, diffusion & osmosis, the different types of solutions and their effect on a cell and the parts of a cell membrane.
Thursday 11/15:
Today we will spend some time reflecting on the test that we took Wednesday and start our next unit with a reading on mitosis.
Friday 11/16:
The rough plan for today will be to complete an internet activity where the students will be learning about the stages of the cell cycle as they try to control the division of the cell. I will try to update more details later in the week.
